“…The basic reasons for the selection of the gasification technology were the high efficiency of the process and the form of generated solid waste, which ensures the minimization of their harmful impact on the environment. The fuel gasification island was developed based on Institute for Chemical Processing of Coal (IChPW) data and literature data on gasification technology in a entrained reactor with a dry fuel feed, based on the Shell technology [46]. This reactor has a very high conversion rate of carbon element and high process efficiencies.…”

“…The method consists in determining the costs of purchasing the equipment of the considered installation (delivery of machines, apparatus, devices), and then using appropriate indicators to estimate sub-costs and total investment costs. For the main units, the indicators determined based on NETL studies [46] and own data were assumed (Table 7). It was assumed that the capital expenditure for the installation is determined as Total Plant Cost (TPC).…”

Closing of Carbon Cycle by Waste Gasification for Circular Economy Implementation in Poland

Domestic coal and waste resources, which are valuable sources of carbon, can support efforts to transform a linear economy into a circular carbon economy. Their use, as an alternative to conventional, imported fossil resources (crude oil, natural gas) for chemical production, provides an opportunity for Poland to solve problems related to competitiveness, security of supply, and sustainable development in various industries. This is important for Poland because it can provide it with a long-term perspective of economic growth and development, taking into account global trends (e.g., the Paris Agreement) and EU legislation. The article presents a concept to support the transformation from linear toward a circular carbon economy under Polish conditions. The carried-out analyses showed that coal, RDF, and plastic waste fuels can be a valuable source of raw material for the development of the chemical industry in Poland. Due to the assumed availability of plastic waste and the loss of carbon in the production process, coal consumption is estimated at 10 million t/yr, both in the medium- and long-term. In case where coal consumption is reduced and an additional source of ‘green hydrogen’ is used, CO2 emissions could be reduced even by 98% by 2050. The presented results show the technical and economic feasibility of the proposed solution and could be the basis for development of the roadmap for transition of the linear to circular economy under Polish condition.

“…The goal of this work is to propose an improved design for CTM process using process intensification concept whereby minimizing the CO 2 emissions from the process. First a base case model is developed by modifying the CTM process reported in literature [33]. Then, three alternative designs have been developed, implying the principles of process intensification to study the feasibility of the proposed designs.…”

Methanol is a clean fuel and an important feedstock for the petrochemical industry. Conventionally, the coal-to-methanol process generates a substantial amount of CO2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coal-to-methanol process using captured CO2 from the gasification plant by implying process intensification. The base case and three alternative designs have been developed using the Aspen Plus to analyze the process performance. The four designs have been compared in terms of their energy consumption, economics, methanol production rate, and carbon emissions while maintaining the gasifier operation conditions, sulfur content in the syngas, and stoichiometric number at the methanol synthesis reactor. Among the developed designs, the most feasible design requires an energy requirement and product cost of 21.9 GJ and $142.5 per ton of methanol product. The study also showed that the coal-to-methanol process assisted with external hydrogen from electrolysis plant for achieving higher production rates and low CO2 emissions is currently not economical due to the high H2 cost.

“…This study aims to investigate and carry out process analysis for chemical-looping-assisted syngas production using Ca 2 Fe 2 O 5 and to compare its performance to ATR. Natural gas composition as described in the National Energy Technology Laboratory (NETL) baseline analysis of the thermodynamic performance for methanol production is used for performing various thermodynamic calculations . The effects of oxygen carrier to natural gas molar ratio, reactor temperature and pressure, and cofeeding steam along with natural gas on the parameters such as syngas yield, fuel conversion, and H 2 :CO ratio are investigated.…”

Thermodynamic and Process Analyses of Syngas Production Using Chemical Looping Reforming Assisted by Flexible Dicalcium Ferrite-Based Oxygen Carrier Regeneration

Syngas production is highly critical to the manufacturing of many value-added products, and its economic prospects can be increased through the enhancement of fuel conversion and the syngas yield. This study explores the thermodynamic characteristics of syngas production through chemical looping reforming (CLR) of natural gas using dicalcium ferrite (Ca2Fe2O5) as the oxygen carrier in a cocurrent moving-bed reactor. The effects of temperature, pressure, and steam addition are studied for both isothermal and adiabatic conditions. A natural gas conversion of 99.78% and a yield of 2.86 mol of syngas/mol of natural gas are obtained for CLR as compared to 95.97% and 2.70, respectively, for autothermal reforming (ATR). A fluidized bed and a countercurrent moving bed are employed for the regeneration of reduced solids using air and a steam/CO2 mixture, respectively, thereby achieving operational flexibility. The syngas yield increases by ∼41% using the steam/CO2 mixture, whereas a high-purity H2 is obtained from the oxidation of reduced solids in pure steam. The process analyses indicate an increase in the effective thermal efficiency from 86.4% to 92.2% and the exergy efficiency from 79.5% to 85.3% on using the Ca2Fe2O5-based CLR over ATR, rendering the syngas production using CLR economically attractive.
